IMPROVEMENT IN PUMPS.

of this specification.

My present invention is intended as an improvement upon the pump for which Letters Patent were granted to me February 9, 1869; and it consists in the suction and force buckets being so arranged that the suction-rod plays through the force-bucket with the water n owing up through the pipe which forms the force-rod, and in which the suction-rods plays,

to the spout. It also consists in the combination, with tlie suction and force buckets thus arranged, of an air-chamber on the cylinderin sucn a manner that the air regulates for each bucket.

In .order to enable others skilled in the art to which my invention appertains to make and use the same, I will now-proceed to describe its construction and operation, referring to the annexed drawing, in which-E Figure l is a longitudinal vertical section of my improved pump, and Fig. 2 is an enlarged side view of the spout.

A represents the cylinder, in which are the suction-bucket B and the force-bucket G. The rod G of the force-bucket is made of gas-pipe or any other suitable pipe, the upper end of which is pivoted to the handle D a short distance from the pivot-point of said handle. B

. is the rod of the suction-bucket B, which rod passes through the force-bucket C and the pipe C and its upper end pivoted to the inner end of the handle D, both the bucket-rods being pivoted on the same side of the pivot-point of the handle. The water passes up through the center pipe C and out through the spout E, connected with said pipe in any suitable manner. The force-bucket C moves about onehalt' the distance of the suction-bucket B, giving a steady stream ot water with a powerful leverage on the water, working admirably in deep wells. Connected with the cylinder A is an air-chamber, G, arranged as shown, so that the air will regulate for both buckets.

Having thus fully describedmy invention, what I claim as new, and desire to secure by Letters Patent, is Y 1. The arrangement in one cylinder, A, of the suction-bucket B and force-bucket G, when the suction-rod B passes through the forcebucket and its rod or pipe C', both being attached to the same end of the handle D and the water passing up through the center rod have hereunto set my hand and seal this lst day of February, 187 2.
